DNSSEC is suppose to protect your DNS requests on the way. Thus one of the endpoint (your client or your trusted recursive dns server) should use DNSSEC. The best is of course on your laptop, as you could trust it. But if you use DNSSEC on your recursive DNS server on your gateway (gateway you trust), you do not need to have it on end clients.
